How Does Training Affect Performance?Students learn about:energy systemsalactacidsystem(ATP/PC) lactic acid systemaerobic systemStudents learn to:• analyse each energy system by exploring:– source of fuel– efficiency of ATP production– duration that the system can operate– cause of fatigue– by-products of energy production – process and rate of recoveryThe human body requires a continuous supply of energy both to meet the needs of its systems and organs and to power muscular contraction for movement.

Body energy is stored in the chemical bonds that join atoms and is released only as needed.

The transformation of food (chemical energy) to energy that the muscles can use (mechanical energy) is the role of energy systems.

The transformation of food (chemical energy) to energy that the muscles can use (mechanical energy) is the role of energy systems.

Energy provided by food is measured in kilojoules (kJ). Carbohydrate and protein supply 16 and 17 kilojoules of energy per gram Fat yields 38 kilojoules per gram.When food is digested, it breaks down to sugars, amino acids and fatty acids.ATP or adenosine-triphosphate is produced and represents the most important substance in energy production.

Jot down some points you were unaware ofin the following VideoATP does not become a waste productIt has the ability to be quickly rebuilt or resynthesisedThe body turns over ATP to the equivalent of 75 per cent of its weight during a 24-hour periodATP needs to be continually rebuilt to enable an energy flow

DID YOU KNOWThe three systems that make ATP available are:the alactacid system (commonly called the ATP/PC system)the lactic acid system (glycolytic system)the aerobic system (oxygen system)
